(54) RADAR DEVICE


(57) A radar device for automotive applications comprises a radar circuit configured to process a radar signal that has a first signal portion and a second signal portion, wherein the first signal portion occupies a first frequency band and the second signal portion occupies a second frequency band that is separate from the first frequency band. An antenna device of the radar device comprises a first and second antenna element that are both coupled to a common signal port of the radar circuit and the radar device is configured to route both the first signal portion and the second signal portion via the common signal port between the radar circuit and the antenna device. The antenna device is a frequency selective antenna device that transduces the first signal portion via the first antenna element and not via the second antenna element and that transduces the second signal portion at least via the second antenna element.
